Battery voltage no start question?

Over the past few weeks my cold morning start has been weak and this morning no start (evening start after the 11 mile morning trek to work is never an issue). Try and jump and no luck - put it on the charger and off to work, get home take off charger no start super weak starter turn over. Cleaned terminals and checked voltage 12.7x on both batteries when connected and disconnected - turn on truck drops to 11.9/12.0 and no start - wait for gliw plugs to cycle off voltage at 12.3x - no start turn key off 12.5 Volts at both batteries.

is it time for new batteries? or is there something else I should look at - no determination on these Napa legend batteries they where in it when I bought it last April and no date markings

thanks for the help

Took connections off starter and reconnected now I get just a thunk from the starter and no turn over whatsoever - battery voltage the same

​​​​is there a good starter option from the local parts stores - napa / orileys or should I go online?

dose everyone recommend the 02 2 bolt gear reduction starter?

Could also be weak batteries tho. I just had to change mine today as they had quite a few years on them and had been run dead a time or two in the cold and now it was to the point I needed a boost every time. I have changed all my battery cable ends and everything as well but these batteries just weren't cutting it at -30c haha

And I'll also add in that if your batteries ever go dead in the cold make sure to take them inside and thaw them out for a day before attempting to charge as a completely dead battery can be frozen solid, just for future reference for readers who have to deal with the cold

Thanks guys - threw a Napa 02 SD gear reduction starter in and the truck is very happy and batteries are fine

- the core alone on this starter is near 4 times the amount I paid for my last starter altogether just thought that was interesting

Do you have the # part of that SD starter?

No worries. I don't know how shipping would be to Mexico though.
